The premise behind these containers is pretty simple:
SAVE FOOD — There are no pumps, motors, or confusing parts. Simply press on the lid and air is forced out through the one-way valve.
SAVE SPACE — Each container nests for convenient storage.
SAVE TIME — The pieces are BPA-free and microwave-, dishwasher- and freezer-safe.
I wasn't completely convinced these little plastic things could save my precious $5 greens, so I put them to the harshest test I could think of:
Could they, if left on my kitchen counter, contain the smell of my family's food scraps for three days?
I started with broccoli stems (which normally would have been eaten but were sacrificed for the sake of this experiment) and added pieces of tomato, banana, kiwi and padding from a package of ground chicken.
By the end of the experiment, the food was moldy and incredibly smelly — but my house wasn't.
This container held in three days' worth of funk, so I feel pretty confident it can keep my lettuce from wilting for a few days.
That said, I'm realistic about what the Orezi Instavac containers can do, and I'm not expecting miracles. They probably won't keep my cauliflower fresh for a month. I'm not looking for my strawberries to stay edible for a three weeks.
I understand that temperature changes can affect the vacuum seal, so I might need to push a bit of air out after a few days. But is that such a big deal? I don't think so.
Bottom line: If I hadn't received the Ozeri Instavac containers to review, I'd probably have purchased a set. The price is good, and they perform a lot better than the Chinese food takeout tubs I have stacked in my cabinet.
